Discover one of Scotland's most iconic castles and the great geological fault that shaped its dramatic setting — all in a single half-day from Aberdeen.

This relaxed half-day tour from Aberdeen (with convenient cruise ship pickup at South Harbour) takes you to Dunnottar Castle, the spectacular clifftop fortress that protected Scotland's Crown Jewels. Along the way you'll walk metamorphosed ocean-floor rocks more than 600 million years old, take in panoramic views across the Highland Boundary Fault, and explore Stonehaven's coastal geology — volcanic flows and ancient river deposits side by side.

Your guide is Steve Adams, a working geologist with 45 years of experience and a knack for making rocks come alive. He'll show you why Dunnottar stands exactly where it does and how Scotland's contrasting landscapes were forged along this single great fault line.

No geology background needed. Most of our guests don't have one.
